Arsenal midfielder Oxlade-Chamberlain has returned to training after his troublesome groin injury.

The Gunners' boss Arsene Wenger still urged caution that there could be a reaction after he returns to training, but is confident the 20-year-old will be fit in time for the World Cup as Roy Hodgson prepares to name his Three Lions squad on Monday.

Hodgson has been in touch with Wenger about both Jack Wilshere and Oxlade-Chamberlain, and his counterpart at the Emirates has given him reassurances.

Wenger said: "If he gets over the next three or four days, he will be available. If he doesn't, then we have to rest him and see. The next three or four days will be vital for him.

"He is desperate to go, and who wouldn't be? But we are in a job where your body responds or it doesn't respond. If it doesn't respond... the body is always stronger. In the end, you need your body to play football.

"He can only go to the World Cup if he is completely fit. It wouldn't be helpful for England for him to go there and not be 100% fit."

But there is bad news for Hodgson as Tottenham full-back Kyle Walker looks as if he will definitely miss out.

Walker, who has been troubled by a pelvic problem for months, was hoping to play in the North Londoners' final game of the season on Sunday, but won't make it.
